> In the current implementation, for a given web service, a C++ class per SOAP fault type
is created (as declared in the WSDL), plus an intermediate XXX_AxisClientException class.
To catch web service errors, you need in your C++ client to add a catch clause on this XXX_AxisClientException,
then call getFault(), then call getCmplxFaultObjectName(), then compare the string with every
possible fault types, then finally call getCmplxFaultObject() and proceed with the actual
exception  handling. 
> There are several problems with this implementation, the two most obvious are:-
> 1. It is not very straightforward.
> 2. The intermediate object is called XXX_AxisClientException where XXX is the name of
the wsdl:service and not the wsdl:portype (what if I want to call different services which
share the same portType, which is a very common scenario here). 
> I would be preferable to have something along these lines (more Axis-Java like): 
> try { 
>         myService->method(); 
> } catch (MyFaultType1 e1) { 
>         // Error handling implementation for MyFaultType1 
> } catch (MyFaultType2 e2) { 
>         // Error handling implementation for MyFaultType2 
> } catch (MyFaultTypeN eN) { 
>         // Error handling implementation for MyFaultTypeN 
> }
